Double-jabbed people in England will no longer have to self-isolate if they are a close contact of a Covid-positive person from today.
People will instead be encouraged to have a PCR test, but it will not be compulsory. The new guidance will apply to people who had their final dose of an approved vaccine
at least 14 days before coming into contact with a positive case.
Those that have not had two doses of the vaccine
will still need to isolate for 10 days.
It comes as former prime minister Gordon Brown urged world leaders to convene an emergency summit to tackle the "scandal" over a lack of global coronavirus vaccines
He called on Joe Biden
and this year's chair of the G20, Italian Prime Minister Mario Draghi, to take action in advance of the September United Nations General Assembly amid rising numbers of deaths in Africa.
According to Mr Brown, Africa, which has only fully vaccinated 1.9 per cent of its population, has been forced to export millions of lifesaving Covid vaccines
to Europe, which has fully vaccinated more than 50 per cent.
